Abstract
PURPOSE The aim of this study was to analyze the impact of calcification on the 12 and 24 months outcomes of the Eluvia™ (Boston Scientific®) drug-eluting stent (DES) for femoropopliteal occlusive disease using three different calcium scoring systems. MATERIAL AND METHODS A single-center, retrospective cohort-study (March-2016 to December-2018) of patients treated with the Eluvia™ DES for femoropopliteal atherosclerosis was performed. Outcomes included primary and secondary patency rates and freedom from target lesion revascularization (FTLR) and were analyzed by comparing the impact of calcium burden according to the following calcium scores: Peripheral Arterial Calcium Scoring System (PACSS) score, number of vessel quadrants affected (0-4) and calcification score per Peripheral Academic Research Consortium (PARC) definitions. RESULTS In total, 111 Patients were included (mean age: 71.2 ± 7.9; 64% male). Most patients presented with Rutherford class 3 (79.9%), followed by class 5 (12.7%), class 4 (10%) and class 6 (6.4%). The mean lesion length was 197.6 ± 108.5 mm and 74.3% of patients had chronic total occlusions. There were no differences in primary patency between the calcification scores at 12 months (PACSS, LogRank = 0.28; quadrants, LogRank = 0.29; PARC, LogRank = 0.42) and 24 months (PACSS, LogRank = 0.13; quadrants, LogRank = 0.42; PARC, LogRank = 0.13). FTLR was significantly lower at 12 months in patients with calcification affecting 3 or 4 quadrants (LogRank = 0.022) but not at 24 months (LogRank = 0.36). CONCLUSIONS In this study, the Eluvia™ DES showed promising performance in calcified disease and the analysis according to the quadrant model predicted an increased risk for TLR at 12 months.

Abstract
OBJECTIVES The objective is to assess the performance of the Eluvia polymer coated drug eluting stent (DES) compared to a bare metal stent (BMS) platform in patients with femoropopliteal arterial disease. METHODS This is a retrospective, single-center analysis. Patients treated with the Eluvia DES (group Eluvia) or the EverFlex BMS (group BMS) for femoropopliteal disease between January 2013 and December 2019 were included. Primary measure outcome of this analysis was the overall mortality. The PTX specific mortality, the primary patency, the amputation free survival (AFS), and the target lesion revascularization (TLR) rates were additionally evaluated. RESULTS A total of 124 patients were treated by BMS deployment, while the Eluvia platform was preferred in 75 subjects. In both groups the majority presented with lifestyle limiting claudication (BMS: 84% vs Eluvia: 73%, p = 0.73). Chronic total occlusions were more frequent in patients treated by BMS (BMS: 71% vs Eluvia: 84%, p = 0.027), whereas the calcification burden (BMS: 81% vs Eluvia: 76%, p = 0.43) and the median lesion length (in mm, IQR) (BMS: 160 (100 to 240) vs Eluvia: 140 (80 to 229), p = 0.17) were comparable. At 24 months, the overall survival (BMS: 93% vs Eluvia: 89%, hazard ratio (HR): 1.20, 95% confidence interval (CI): 0.55 to 2.64, p = 0.64) and the PTX specific survival (BMS: 95% vs Eluvia: 95%, HR: 1.28, 95% CI: 0.41 to 4.02, p = 0.67) did not differ significantly between the two platforms. No significant difference was observed regarding the 24 months primary patency rate (BMS: 66% vs Eluvia: 78%, HR: 0.65, 95% CI: 0.37 to 1.15, p = 0.18), the freedom from TLR (BMS: 83% vs Eluvia: 89%, HR: 0.81, 95% CI: 0.39 to 1.68, p = 0.572), and the AFS (BMS: 93 vs Eluvia: 89%, HR: 1.20, 95% CI: 0.55 to 2.64). The Cox regression analysis revealed a higher mortality risk among patients with chronic limb-threatening ischemia (CLTI) (HR: 3.14, 95% CI: 1.61 to 6.14, p = 0.008), chronic obstructive pulmonary disease (COPD) (HR: 4.65, 95% CI: 2.14 to 10.09, p = 0.001), in octagenerians (HR: 4.40, 95% CI: 1.92 to 10.44, p = 0.005), and in patients not on statins at baseline (HR: 2.44, 95% CI: 1.19 to 4.99, p=0.014). CONCLUSIONS In this cohort, the use of the Eluvia DES did not increase the risk for mortality compared to BMS deployment. CLTI, COPD, advanced age, and the lack of statin therapy at baseline were associated with a higher risk for death.

Abstract
PURPOSE To report the performance of surgical treatment (ST), hybrid treatment (HT), and endovascular treatment (ET) for patients with acute limb ischemia (ALI). METHODS This is a retrospective, comparative study of all consecutive patients with ALI treated in 2 tertiary centers between April 2010 and April 2020. Amputation and/or death (amputation-free survival; AFS) was the primary composite endpoint. Mortality, major amputation, and reintervention during follow-up were additionally analyzed. Proportional hazards modeling was used to identify confounders, results are presented as hazard ratio (HR) and 95% confidence intervals (CIs). RESULTS In total, 395 patients (mean age=71.1±13.6 years; 51.1% female) were treated during the study period. Surgical treatment was preferred in 150 patients (38%), while 98 were treated by HT (24.8%) and 147 by ET (37.2%). Rutherford class IIa was the most common clinical presentation in the ET group (50.3%), whereas Rutherford IIb was most common in the ST (54%) and HT (48%) groups (p<0.001). Significantly, more patients presented with a de novo lesion in the ST and HT groups (79.3% and 64.3%, respectively) compared with ET (53.7%; p<0.001). Median follow-up was 20 months (range=0-111 months). In the multivariate analysis, ET showed significantly better AFS during follow-up compared with ST (HR=1.89, 95% CI=1.2-2.9, p<0.001) and HT (HR=1.73, 95% CI=1.1-3.1, p<0.001). Mortality during follow-up was also significantly lower after ET compared with ST (HR=2.21, 95% CI=1.31-3.74, p=0.003) and HT (HR=2.04, 95% CI=1.17-3.56, p=0.012). Endovascular treatment was associated with lower amputation rate compared with ST (HR=2.27, 95% CI=1.19-4.35, p=0.013) but was comparable with HT (HR=2.00, 95% CI=0.98-4.06, p=0.055). Reintervention rates did not differ significantly between the groups (ET vs ST: HR=1.52, 95% CI=0.99-2.31, p=0.053; ET vs HT: HR=1.3, 95% CI=0.81-2.07, p=0.27). CONCLUSION Endovascular treatment for ALI was associated with improved AFS and comparable reintervention rates compared with open surgical and hybrid therapy. CLINICAL IMPACT Treatment of acute lower limb ischemia remains a challenge for clinicians with high morbidity and mortality rates. Endovascular revascularization is considered first line treatment for many and hybrid treatments are becoming more common, however data is limited to either old trials, small series or with short follow-up. We present herein our 10-year experience with all available devices and techniques for open surgical, endovascular and hybrid acute limb ischemia treatments and compare their outcomes.

Abstract
OBJECTIVE Bullying, undermining behaviour, and harassment (BUH) may exist in healthcare settings, impacting on patient care. The aim of this international study was to evaluate the characteristics of BUH experienced by physicians treating vascular diseases at various career stages. METHODS This was an anonymous international structured non-validated cross-sectional survey distributed via relevant professional societies in collaboration with the Research Collaborative in Peripheral Artery Disease. The survey was disseminated through societies' newsletters, emails, and social media. Data were collected online, allowing free text entries alongside structured multiple choice questions based on previous surveys. Demographics, geographical information, and data relating to stage and training environment were collected. RESULTS Of 587 respondents from 28 countries, 86% were working in vascular surgery, mostly at a university hospital (56%); 81% were aged between 31 and 60 years, 57% were working as a consultant, and 23% as a resident. Respondents were mostly white (83%), male (63%), heterosexual (94%), and without disability (96%). Overall, 253 (43%) reported experiencing BUH personally, 75% had witnessed BUH toward colleagues, and 51% witnessed these in the last 12 months. Female sex and non-white ethnicity were associated with BUH (53% vs. 38% and 57% vs. 40% respectively; p < .001 in both cases). While working as a consultant, 171 (50%) reported experiencing BUH, more often among females, non-heterosexuals, those who were not working in their country of birth, and non-white people. Specialty and hospital type were not associated with BUH. CONCLUSION BUH remains a major problem in the vascular workplace. Female sex, non-heterosexuality, and non-white ethnicity are associated with BUH at various career stages.

Abstract
OBJECTIVES Intravascular lithotripsy (IVL) followed by drug-coated balloon (DCB) angioplasty might be a valuable alternative to surgery for calcified common femoral artery (CFA) atherosclerotic disease. Nonetheless, the 12 months performance of this treatment strategy remains unknown. This study reports on the 12 months outcomes of IVL with adjunctive DCB angioplasty for calcified CFA lesions. METHODS This is a retrospective single-center, single-arm study. Consecutive patients treated by IVL and DCB for calcified CFA disease between February 2017 and September 2020 were evaluated. The primary measure outcome of this analysis was primary patency. Procedural technical success (<30% stenosis), freedom from target lesion revascularization (TLR), secondary patency, and overall mortality were additionally analyzed. RESULTS Thirty-three (n=33) patients were included in this study. The majority presented with lifestyle limiting claudication (n=20, 61%), 52% (n=17) of the patients had chronic kidney disease (CKD) and 33% (n=11) had diabetes. The procedural technical success was 97% (n=32). A flow-limiting dissection post IVL was observed in 2 patients (6%) and a peripheral embolization in a single patient (3%), while the bail-out stenting rate amounted to 12% (n=4). No perforation was observed. The median length of hospital stay was 2 days (interquartile range 2-3). At 12 months, the primary patency was 72%. The freedom from TLR and the secondary patency rates were 94% and 88%, respectively. The 12-month survival amounted to 100% and 75% (n=25) of the patients were asymptomatic or presented with mild claudication. The presence of chronic limb-threatening ischemia (CLTI) (hazard ratio [HR], 0.92; confidence interval (CI); 0.18-4.8, p=0.7) or CKD (HR, 1.30; 95% CI, 0.29-5.8; p=0.72), as well as the use of a 7 mm IVL catheter (HR, 0.59; 95% CI, 0.13-2.63; p=0.49) or of high-dose DCB (HR, 0.68; 95% CI, 0.13-3.53; p=0.65) did not influence the primary patency. CONCLUSIONS In this study, the combination of IVL and DCB angioplasty for calcified CFA disease was associated with low risk for periprocedural complications, acceptable 12 months clinical outcomes, and low rates of reinterventions. CLINICAL IMPACT Intravascular lithotripsy in combination with DCB angioplasty can be an alternative to surgery in highly selected patients with CFA atherosclerotic disease. In this Cohort the combination therapy lead to acceptable clinical results and low reintervention rates at 12 months.

Abstract
INTRODUCTION The combination of intravascular lithotripsy (IVL) and drug-coated balloon (DCB) angioplasty for calcified peripheral lesions is associated with promising short-term results. However, data regarding the 12 months performance of this treatment option is missing. This study reports on the outcomes of IVL and DCB angioplasty for calcified femoropopliteal disease. METHODS Patients treated with IVL and DCB for calcified femoropopliteal lesions between February 2017 and September 2020 were included into this study. The primary outcome measure of this analysis was primary patency. Secondary patency, freedom from target lesion revascularization (TLR) and overall mortality were additionally analyzed. RESULTS Fifty-five (n = 55) patients and 71 lesions were analyzed. Most patients presented with long-term limb-threatening ischemia (n = 31, 56%), 47% (n = 26) were diabetics, and 66% (n = 36) had long-term kidney disease. The median lesion length was 77 mm (interquartile range: 45-136), and 20% (n = 14) of the lesions were chronic total occlusions (CTOs). Eccentric calcification was found in 23% of the vessels (n = 16), and circumferential calcium (peripheral arterial calcium scoring system [PACSS] Class 3 and 4) was present in 78% (n = 55) of the treated lesions.The technical success after IVL amounted to 87% (n = 62) and the procedural success to 97% (n = 69). A flow-limiting dissection was observed in 2 cases (3%). Both the rates of target lesion perforation and distal embolization were 1% (n = 1). A bail-out scaffold was deployed in 5 lesions (7%). At 12 months the Kaplan-Meier estimate of primary patency was 81%, the freedom from TLR was 92% and the secondary patency 98%. The overall survival amounted to 89%, while the freedom from major amputation to 98%. The presence of eccentric disease, CTOs, or PACSS Class 4 did not increase the risk for loss of patency or TLR. CONCLUSIONS In this challenging cohort of patients, the use of IVL and DCB for calcified femoropopliteal lesions was associated with promising 12 months outcomes and an excellent safety profile.

Abstract
Abstract
Background
Adult congenital heart disease (ACHD) survival has dramatically improved in recent decades. As such, clinicians now face the complex long-term interactions of congenital and chronic heart diseases. One area of continuing mortality in this group is arrhythmias, especially in those with cardiovascular implantable electronic devices (CIEDs). With these developments in survival, the long-term outcomes of the CIED systems and their effects on mortality are beginning to be elucidated.
Aims
This study aims to compare the effects of system location, surgical history, patient demographics and congenital disease complexity on lead survival, complication distributions and patient mortality in ACHD CIED patients.
Methods
A retrospective cohort of 250 ACHD CIED patients with follow up at a heart centre was collated from clinical correspondence letters and CEID records. Data was collected on demographics, mortality and lead survival and complications. Survival data was analysed with Kaplan-Meier (KM) curves and hazard ratio tests.
Results
Complex ADHD patient survival was less than the non-complex cohort (HR 0.38, 95% CI 0.22–0.67, p<0.01). Lead survival was longer in non-surgical patients (HR 1.42, 95% CI 1.13–1.78, p<0.01) and longer in female patients (HR 1.35, 95% CI 1.07–1.69, p<0.01) (Figure 1). No significant differences in mortality or lead survival were seen between epicardial and transvenous systems.
Conclusions
Complex ACHD is associated with worse patient mortality in CEID patients. Surgical history and male gender are associated with worsened lead survival.

Abstract
Introduction: Antegrade wire-catheter crossing remains the primary approach for femoropopliteal interventions. Nonetheless, data reporting on crossing failure are limited. Aim of this study is to identify risk factors for antegrade crossing failure in patients with femoropopliteal chronic total occlusions (CTOs). Methods: This is a single-center, retrospective analysis. Patients with femoropopliteal CTOs treated between May 2018 and February 2020 were included into this study. Primary endpoint of this analysis was primary crossing success defined as successful antegrade crossing without the use of retrograde access, crossing or re-entry devices. The assisted crossing success was additionally analyzed. A logistic regression analysis identified risk factors for failed primary antegrade crossing. Results: Data from 300 patients were analyzed. The majority (n=183, 61%) presented with lifestyle limiting claudication. The mean lesion length was 180 mm [interquartile range (IQR) 100–260 mm], whereas the median CTO length was 100 mm (IQR=50–210 mm). A chronic total occlusion crossing approach based on plaque morphology (CTOP) type I configuration was observed in 9% (n=26) of the lesions, type II in 61% (n=183), type III in 8% (n=25), and type IV in 66 CTOs (n= 66, 22%). Severe calcification based on the Peripheral Arterial Calcium Scoring Scale (PACSS), Peripheral Academic Research Consortium (PARC), and 360° grading systems was identified in 17%, 24%, and 28% of the lesions, respectively. A contralateral femoral access was used in 278 cases (93%). The primary crossing success amounted to 70% (n=210). The use of a re-entry device in 28 patients (9%) or of a combined antegrade–retrograde approach in 11% (n=34) of the cases increased the assisted crossing success to 89% (n=267). The presence of calcification (odds ratio [OR]=4.2, 95% CI=1.7–10.2) or of circumferential calcium (OR=2.5, 95% CI=1.3–4.9), a CTOP class ΙΙΙ or ΙV (OR=1.9, 95% CI=1.4–2.6), a proximal superficial femoral artery (SFA) occlusion (OR=3.5, 95% CI=1.7–7.4) and a CTO at P3 (OR=4.1, 95% CI=1.5–10.8) were associated with an increased risk for antegrade crossing failure. Conclusions: In this study, chronic total occlusions (CTO) morphology, calcification burden, and lesion’s location were identified as independent risk factors for failed antegrade crossing. Nonetheless, the use of alternative crossing strategies significantly increased the overall crossing success.

Abstract
OBJECTIVE To report outcomes following endovascular revascularisation for severe aorto-iliac occlusive disease (AIOD) using covered (CS) or bare metal (BMS) stent(s). METHODS This was a retrospective cohort study including patients who underwent treatment with CS or BMS for AIOD between November 2012 and March 2020 in 12 European centres. Outcome measures included death, freedom from target lesion revascularisation (TLR), major amputation, and major adverse cardiac and cerebrovascular events (MACCE). RESULTS Overall, 252 patients (53% males; mean age 65 ± 10 years) were included (102 with a bare metal and 150 with a covered aortic stent); 122 (48%) presented with chronic limb threatening ischaemia (CLTI). Severe arterial calcification was noted in > 65% of patients, 70% presented with Trans-Atlantic Societies Consensus (TASC) D lesions, 32% and 46% had aortic or iliac chronic total occlusion (CTO), respectively. Median follow up was 17 months (range 6 - 40; none lost to follow up). Median inpatient stay was two days (range two to four). During the first 30 days, two patients died (both with covered aortic stents, because of cardiovascular events), none required TLR, two (1%) patients had a major amputation (all presented with CLTI), and three (1%) had a MACCE. At 17 months, mortality (BMS 14% vs. CS 7%, hazard ratio [HR] 0.97, 95% confidence interval [CI] 0.42 - 2.26, p = .94, log rank test) and TLR (11% vs. 10%, HR 1.98, 95% CI 0.89 - 4.43, p = .095) did not differ statistically significantly between the two groups; only three patients had a major limb amputation during late follow up (all with a covered stent). In a multivariable model, the use of an aortic CS did not influence TLR. In a conditional Cox regression, however, the concomitant use of aortic and iliac CSs was associated with improved freedom from TLR. CONCLUSION Endovascular reconstruction with aortic CSs or BMSs for severe AIOD showed comparable midterm performance. The use of both aortic and iliac CSs seems to be associated with reduced TLR.

Abstract
Abstract
Introduction
Orthopaedic undergraduate education is both minimal and variable across UK medical schools. Furthermore, the clinical skills required to treat musculoskeletal injuries have been found inadequate by several studies assessing UK medical graduates.
Method
Orthopaedic revision courses organized by the student surgical society consisted of lectures and workshops covering clinical orthopaedic knowledge and skills required for university assessments. Five identical courses were run between December 2017 and December 2019 following the completion of fourth year’s musculoskeletal clinical block. Course tutors ranged from foundation year doctors (57%) to orthopaedic consultants and trainees (43%). An anonymous feedback form was handed out at each event and 5-point Likert scale questioning assessed participant perceptions prior to and following the course.
Results
This course led to a significant mean increase in students’ perceived knowledge levels with an average increase of 0.96 (19.2%) across all clinical examinations and lectures (p < 0.01). Tutor grade did not affect mean participant self-reported value of station, with stations taught by consultants and surgical trainees showing similar results to stations taught by FY doctors (p = 0.776).
Conclusions
The feedback revealed significant increases in student self-reported knowledge levels while poor pre-course scores reported might suggest inadequate coverage of orthopaedics in the undergraduate curriculum. The similarity in results when assessing the quality of tutorship suggests that FY doctors can be equally as valuable teaching tools for such courses as surgical trainees and consultants. These results suggest 1-day orthopaedic revision courses of this format can be highly beneficial in supplementing the undergraduate curriculum.

Abstract
Abstract
Introduction
Deep sternal wound infections (DSWI) are a serious complication following cardiac surgery that comprise of any infection penetrating the subcutaneous tissue of the sternum. DSWI have been found to increase mortality and worsen prognostic outcomes following surgery.
Method
We conducted a retrospective cohort study using hospital e-records from 2000 to 2017 of all adult patients operated on with a median sternotomy at our institution. Univariate and multivariate analysis along with mortality and Kaplan-Meier survival curves compared the DSWI population against the remaining study population, using SPSS-25 software.
Results
Of 15521 total patients in the study, 145 (0.9%) suffered a DSWI. Variables that were associated with DSWI included age at operation (p = 0.019), gender (p = 0.007), BMI (p = 0.001), diabetes (p < 0.0001), renal disease (p = 0.008), operative urgency (p = 0.007), type of operation (p = 0.02), Euroscore (p = <0.0001), bypass-time (p = 0.038) and crossclamp-time (p = 0.008). A logistic regression encompassing significant variables revealed that gender (p = 0.031 CI 1.45-1.96), BMI (p < 0.0001 CI 1.03-1.10), diabetes (p = 0.007 CI 1.20-3.67) and type of operation (p = 0.018 CI 1.23-1.87) remained significant when covariate contribution was eliminated. DSWI subgroup mortality was insignificant at 30 days (3.4%vs2.9%, p = 0.68) but significantly worse at 90 days (8.3%vs3.7%, p = 0.004) and at 1 year (17.2%vs5.4%, p < 0.0001). Kaplan-Meier analysis depicted a significantly worse survival distribution for the DSWI population compared to rest of study (Log-Rank<0.05).
Conclusions
At our centre, DSWI are attributable to certain modifiable and set demographics and contribute heavily to medium-term mortality. A better understanding of DSWI risk factors may pinpoint those at risk and benefit the multidisciplinary team to ultimately reduce the rate of DSWI.

Abstract
Asylum-seekers experience high levels of traumatic events pre-, post- and during migration. Poly-traumatisation is associated with complex post-traumatic stress disorder (CPTSD), which has not yet been extensively explored in this population. CPTSD is a prevalent and highly disabling disorder in the present population requiring culturally sensitive diagnostic and treatment approaches. In this service evaluation, we evidence the high prevalence of CPTSD in an asylum-seeking sample and its association with greater distress compared with PTSD. We outline the treatment needs of asylum seekers with CPTSD.

Abstract
OBJECTIVES The aim of this study was to evaluate the 2-year performance of a polymer-based drug-eluting stent (DES) for the treatment of complex femoropopliteal lesions. BACKGROUND Despite the promising early outcomes of the Eluvia DES, the long-term safety and efficacy of the device in a real-world scenario remain unclear. METHODS Between March 2016 and December 2018, 130 patients (137 lesions) with symptomatic femoropopliteal disease were included in this study. The primary outcome measure of this analysis was primary patency. Secondary patency, freedom from target lesion revascularization, freedom from surgical conversion, and overall mortality and morbidity were additionally analyzed. RESULTS The majority of patients presented with lifestyle-limiting claudication (n = 90 [69%]). The mean lesion length was 194 ± 108 mm, 74% of the lesions (n = 101) were chronic total occlusions, and 72% (n = 99) were calcified. Moderate to severe calcification (Peripheral Arterial Calcium Scoring Scale score 3 or 4) was observed in 48% of the treated vessels (n = 67). At 24 months, the Kaplan-Meier estimate of primary patency was 71%, whereas both the secondary patency rate and freedom from target lesion revascularization were 80%. Overall survival amounted to 85%. Freedom from major amputation was 98%, while freedom from surgical conversion was 89%. Degeneration of the vessel wall was observed in 27 lesions (20%). CONCLUSIONS In this study, use of the Eluvia polymer-based DES for the treatment of complex femoropopliteal disease showed promising 2-year results. Nonetheless, a relatively high rate of vessel wall degeneration was observed after DES deployment.

Abstract
Background:CD4+ T cells with cytotoxic functions (CD4+ CTL) have gained attention in recent years. Accumulating evidence supports their importance in defense against human viral infections such as CMV1, EBV2, dengue3, HIV4, 5 and SARS-CoV-26. Moreover, expansion of so called CD28null cytotoxic CD4+ T cells have been reported in the blood of patients with rheumatic diseases such as rheumatoid arthritis (RA)7, myositis8 and vasculitis9 as well as in cardiovascular diseases10.Objectives:Here, we aimed to investigate the presence and clonal expansion of CD4+ CTL in the peripheral blood (PB) and synovial fluid (SF) of RA patients using single cell technologies.Methods:We assessed the expression of cytotoxic effector molecules and transcription factors in CD4+ T cells in synovial fluid (n=21) and paired peripheral blood (n=16) from ACPA- and APCA+ RA patients by multi-parameter flow cytometry. We performed single cell sequencing, in combination with 5´ TCRab sequencing, on purified CD4+ T cells from the peripheral blood (PB) and synovial fluid (SF) of ACPA+ RA patients (n=7).Results:Flow cytometry experiments show that Granzyme-B+ Perforin-1+ CD4+ CTL are significantly increased in the SF of ACPA+ RA patients as compared to ACPA- RA patients (p=0.0072). The presence of CD4+ CTL could be confirmed by single cell sequencing in SF of each ACPA+ RA patient tested (n=7). Moreover, we found that the adhesion G-protein coupled receptor GPR56 is selectively expressed on the recently described peripheral helper (TPH) T-cell subset11 and associates with the expression of tissue resident memory markers LAG-3, CXCR6 and CD69. In blood, we confirmed a previous report12 showing that GPR56 delineates cytotoxic CD4+ T cells. Finally, expanded TCR clones expressing cytotoxic effector molecules were identified in synovial fluid of ACPA+ RA patients and, for some patients, in their corresponding peripheral blood.Conclusion:We identified GPR56 as a marker of TPH cells in SF of ACPA+ RA patients that associates with tissue residency receptors. The combination of single cell sequencing and multi-parameter flow cytometry highlights the importance of CD4+ CTL in ACPA+ RA and suggests a potential therapeutic target (Figure 1).References:[1]Casazza J.

Abstract
Abstract
Introduction
Cardiac surgery in octogenarians contains many age-specific perioperative risk factors and outcomes yet to be fully understood.
Method
All adults (N = 4957) undergoing cardiac surgery between 2011-2017 at our institution were retrospectively studied, encompassing 312 octogenarians. Data was evaluated with univariate and multivariate testing and mortality with Kaplan-Meier and cox-regression analyses.
Results
Compared to septuagenarians, octogenarians revealed more patients having previous surgery (p = 0.016), less diabetic patients (p = 0.034), lower BMI (0.002), and longer hospital stay (p < 0.000). Compared to rest of study, octogenarians contained more females (p = 0.012), a greater Euroscore (p < 0.000), spent longer in ITU (p = 0.001) and contained more ITU readmissions (p = 0.023). The octogenarians did not contain significant 30- and 90-day mortality but revealed significant mortality at 1-year versus septuagenarians (p = 0.039) and rest of study (p = 0.001). Variables testing significant in a multivariate regression were inserted into a cox-regression that found octogenarian group-membership to be insignificant (p = 0.051) in a 12-covariate model. Independent risk factors for mortality included emergency surgery (p = 0.04), reoperation (p < 0.000), cardiac procedure (p = 0.007), ITU time (p = 0.041) and diabetes (p = 0.023).
Conclusions
We report specific differences for octogenarians in perioperative characteristics along with promising short- and medium-term survival. Such outcomes must constantly be monitored so that cardiac surgery can be further tailored to this elderly cohort.

Abstract
Evidence suggests that sexual minorities (e.g., those identifying as lesbian, gay, or bisexual) experience increased rates of depression compared to heterosexual individuals. Minority stress theory suggests that this disparity is due to stigma experienced by sexual minorities. Stigma processes are proposed to contribute to reduced coping/support resources and increased vulnerability processes for mental health problems. This review provided a systematic examination of research assessing the evidence for mediating factors that help explain such disparities. A literature search was conducted using the databases PubMed, PsycINFO, and Web of Science. The review included 40 identified studies that examined mediators of sexual minority status and depressive outcomes using a between-group design (i.e., heterosexual versus sexual minority participants). Studies of adolescents and adult samples were both included. The most common findings were consistent with the suggestion that stressors such as victimization, harassment, abuse, and increased stress, as well as lower social and family support, may contribute to differing depression rates in sexual minority compared to heterosexual individuals. Differences in psychological processes such as self-esteem and rumination may also play a role but have had insufficient research attention so far. However, caution is needed because many papers had important methodological shortcomings such as the use of cross-sectional designs, inferior statistical analyses for mediation, or measures that had not been properly validated. Although firm conclusions cannot be drawn, the current evidence base highlights many factors potentially suitable for further exploration in high-quality longitudinal research or randomized studies intervening with the potential mediators.

Abstract
PURPOSE To report the outcomes of surgical (ST), endovascular (ET), and hybrid (HT) treatment in cancer patients with acute limb ischemia (ALI). MATERIALS AND METHODS A multicenter retrospective registry collected 139 patients (mean age 72.3±12.4 years; 73 men) with ALI and active malignancy treated by ET (41, 29%), ST (70, 51%), or HT (28, 20%) in 7 European centers between July 2007 and February 2019. In 22 cases (16%) ALI was the first manifestation of the malignancy. Lung cancer was the most common diagnosis (38, 27%). The primary composite outcome was amputation-free survival (AFS). Overall survival, amputation-free time (AFT), and reintervention-free time (RFT) were also assessed. Cox regression analysis was applied to identify independent risk factors for the primary and secondary outcomes. Results are presented as the hazard ratio (HR) and 95% confidence intervals (CIs). RESULTS ET was associated with improved 12-month AFS compared with both ST (HR 2.27, 95% CI 1.20 to 4.28, p=0.002) and HT (HR 2.14, 95% CI 1.09 to 4.18, p=0.008). ST (HR 2.50, 95% CI 1.19 to 5.53, p=0.003) and HT (HR 3.10, 95% CI 1.45 to 6.65, p<0.001) were related to an increased risk for mortality compared with ET. At 12 months, the AFT was similar between the 3 groups (ET vs ST: HR 1.52, 95% CI 0.51 to 4.53, p=0.45 and ET vs HT: HR 1.21, 95% CI 0.36 to 4.11, p=0.73). The 12-month RFT also did not differ significantly between the 3 treatment options (ET vs ST: HR 1.10, 95% CI 0.49 to 2.46, p=0.79 and ET vs HT: HR 0.51, 95% CI 0.22 to 1.17, p=0.19). ST and/or HT increased the risk for the major amputation and/or death (HR 1.76, 95% CI 1.05 to 2.05, p=0.03), while Rutherford class I ischemia (HR 0.12, 95% CI 0.02 to 0.90, p=0.04) and previous vascular interventions on the index limb (HR 0.55, 95% CI 0.32 to 0.97, p=0.04) showed a protective effect. CONCLUSION In patients with ALI and active malignant disease, ET was associated with increased AFS and overall survival compared with both ST and HT, while the limb salvage and reintervention rates were comparable among the 3 groups.

Abstract
Purpose: To report the outcomes from the observational SURPASS
registry, which was created to assess the performance of the Conformable TAG
(CTAG) stent-graft with the Active Control System (ACS) in patients undergoing
thoracic endovascular aortic repair (TEVAR) in a real-world setting.
Materials and Methods: The SURPASS registry
(ClinicalTrials.gov; identifier NCT03286400) was an
observational, prospective, single-arm, post-market, international study that
enrolled patients undergoing TEVAR using the CTAG with ACS for both acute and
chronic thoracic aortic disease between October 2017 and July 2018. The CTAG
with ACS features 2-stage deployment of the stent-graft and an optional
angulation mechanism that modifies only the proximal end of the stent-graft.
During the observation period, 127 patients (mean age 67.1±12.1 years, range
27–86; 92 men) were enrolled and treated for an array of aortic pathologies,
including chronic and acute lesions and 4 ruptured descending thoracic
aneurysms. The primary outcome of this study was technical success; secondary
outcomes were clinical success and major adverse events at 30 days and 12
months. The numbers of 2-stage device deployments and applications of the
angulation mechanism were recorded, along with the reasons for use.
Results: Technical success of the TEVAR was 97.6% owing to
unintentional partial coverage of supra-aortic branches in 3 cases (the vessels
were patent on imaging). The stent-graft was repositioned at its intermediate
diameter in 79 patients (62.2%), and the angulation feature was applied in 64
cases (50.4%), mainly to improve proximal wall apposition and orthogonality in
the aorta. The desired effect was achieved in 60 cases (93.8%). There was no
device compression, bird-beak configuration, fracture, or graft occlusion. The
30-day and 12-month clinical success rates were 97.6% and 92.9%, respectively.
There were 3 aorta-related deaths at 30 days and a further 3 at 12 months.
Fatalities were due to a retrograde type A dissection (0.8%), paraplegia, bowel
ischemia, sepsis in the setting of a mycotic aneurysm, aneurysm rupture post
aortoesophageal fistula, and multiorgan dysfunction syndrome. Three endoleaks (2
type Ia and 1 type III) required reintervention. Conclusion: In the
SURPASS registry, the use of the CTAG device with ACS showed promising outcomes
despite the challenging pathologies. The new delivery system enables a
controlled staged delivery with in situ adjustments during positioning,
facilitating the treatment of complex aortic disease.

Abstract
OBJECTIVES The aim of this study was to assess the performance of the fluoropolymer-based paclitaxel-eluting stent (PES) in long femoropopliteal lesions. BACKGROUND The new-generation fluoropolymer-based PES showed promising outcomes in short femoropopliteal lesions. The main feature of the stent is its controlled and sustained paclitaxel release over 12 months. However, the safety and efficacy of this technology in longer femoropopliteal lesions remain unclear. METHODS Between March 2016 and March 2017, 62 patients were included in this analysis. Indications for fluoropolymer-based PES deployment were insufficient luminal gain or flow-limiting dissection after plain old balloon angioplasty in a femoropopliteal lesion. Primary patency, freedom from target lesion revascularization, amputation-free survival, and paclitaxel-related adverse events were retrospectively analyzed for up to 1 year of follow-up. RESULTS Lesions were de novo in 84% of patients. Mean lesion length was 20 ± 12 cm, and 79% of the lesions (n = 49) were chronic total occlusions. Moderate or severe calcification was present in 42% of the lesions (n = 26). Stent implantation involved the distal superficial femoral artery and the proximal popliteal artery in 76% (n = 47) and 44% (n = 27) of patients, respectively. The Kaplan-Meier estimate of primary patency and freedom from target lesion revascularization was 87%. Amputation-free survival was 100% for patients with claudication (n = 32 [52%]) and 87% in patients with critical limb ischemia (n = 30 [48%]) (hazard ratio: 6.3; 95% confidence interval: 1.25 to 31.54; p = 0.052). Five aneurysm formations of the treated segments (8%) were thought to be attributable to paclitaxel. CONCLUSIONS The fluoropolymer-based PES showed promising 1-year clinical and angiographic outcomes in real-world long femoropopliteal lesions. The long-term impact of aneurysm formation remains to be further investigated.

Abstract
Abstract
BACKGROUND
To explore the incidence and clinical phenotype of serious neurological adverse events (NAEs) in cancer patients who received immunotherapy with checkpoint inhibitors (ICIs) at two institutions.
MATERIAL AND METHODS
We reviewed files of cancer patients who were treated with ICIs from 2010 to 2018 and then searched for ICIs-related NAEs.
RESULTS
We identified 1185 ICIs-treated patients. Males and females were 63.7% and 36.3%, respectively, with a mean age of 63.4±7.3 years-old. Nivolumab was given to 536 (45.2%) patients, Pembrolizumab to 301 (25.4%) patients, Atezolizumab to 135 (11.4%), Ipilimumab to 104 (8.8%), Durvalumab-Tremelimumab to 77 (6.5%), and other ICIs to 32 (2.8%). Of those patients, 24 (2%) developed a ICI-related NAE. No differences were identified in age, sex, tumor type and class of ICIs between patients who developed neurotoxicity compared to those without neurologic adverse events. The distribution of NAE by agent was: Nivolumab (2.1%), Pembrolizumab (2%), Atezolizumab (1.5%), Ipilimumab (1%), Durvalumab-Tremelimumab (3.9%), and others (2.8%). The median number of cycles received before NAEs onset were 4.5 (1–10), and the median time was 110 days. PNS involvement was evident in 14 patients (58.3%) and CNS involvement in 41.7%, while 2 patients with aseptic meningitis also presented polyradicular involvement. Among PNS complications, there were 5 cases (20.8%) with axonal sensory neuropathies, 4 (16.7%) with Guillain-Barre-like syndromes, 4 (16.7%) with muscle involvement (myositis and myasthenias), and one with other syndromes. Seven patients (50%) with PNS-related NAEs were treated with steroids, 2 (14.3%) with IVIG, and 5 (35.7%) remained untreated. In general the outcome was good after ICIs discontinuation, with about half of patients improving or completely resolving NAEs.
CONCLUSION
ICIs-related NAE although rare overall, might be severe, and are mostly represented by neuromuscular complications. Early discontinuation of ICIs and possibly treatment with immune-modulating therapies should early be initiated to achieve a favourable neurological outcome

Abstract
Despite the continuous evolution of endovascular therapy, severe calcification remains a major issue for the minimally invasive treatment of superficial femoral artery (SFA) disease. The presence of calcium might negatively affect both the crossing of peripheral lesions and outcomes of all available treatment modalities and is therefore associated with unfavorable acute and long-term results. This manuscript summarizes the challenges raised from severe calcified atherosclerotic lesions and presents the outcomes of the various endovascular modalities in the treatment of calcified SFA disease.

Abstract
Purpose: To evaluate the safety and feasibility of treating calcified, stenotic common femoral arteries (CFAs) using the Peripheral Intravascular Lithotripsy (IVL) System. Methods: An analysis was performed of 21 patients (mean age 71.9±10.1 years; 16 men) across 3 sites with calcified CFA stenoses treated with the Peripheral IVL System. The outcomes of interest were the ability to deliver IVL to the target lesion, the increase in acute gain, the reduction in diameter stenosis, the rate of provisional stenting, and angiographically defined complications. Results: Access to the target lesion and delivery of treatment by the IVL catheter were successful in all 21 patients. Post treatment mean diameter stenosis was 21.3%, representing an acute mean lumen gain of 3.1±1.3 mm (range 0.7–5.2). Vascular complications were minimal, with only 5 type B (non-flowing-limiting) dissections reported. The profunda femoris artery was patent in all patients following IVL, and none of the subjects experienced a perforation, distal embolization, thrombus, no reflow, or abrupt closure. Conclusion: These early results demonstrate that calcified, stenotic CFA lesions can be safely and successfully treated using the Peripheral IVL System.

Abstract
e15082 Background: Peripheral neuropathy (PN) is widely recognised among the major non-haematological dose- limiting toxicities of oxaliplatin (OXL) which is used to treat advanced or metastatic colorectal cancer (CRC). OXL induces two clinically distinct forms of PN. The acute transient syndrome and the chronic OXL-induced peripheral neuropathy (OXLIPN). The integrin beta-3 (ITGB3) polymorphism at residue 33 (L33P) has been previously associated with altered adhesion ability and ERK2 activation. Thus it may affect neuronal survival. The aim of the current study was to investigate the role of the ITGB3 polymorphism at residue 33 in the development of chronic OXLIPN. Methods: Thirty four patients with advanced CRC were genotyped. All patients, 22 males and 12 females had received adjuvant chemotherapy consisting of 12 courses of the formal FOLFOX-4 regimen. Following the discontinuation of treatment, 20 of the patients (58.8 %), developed OXLIPN, whereas the remaining 14 (41.2%) patients remained unaffected with normal peripheral nerve function. The grading of the OXLIPN severity was defined by Total Neuropathy scores, corresponding to the WHO grading scales 1–3 for chemotherapy-induced PN. Genotyping was performed using allele specific primers and sybr green in real time polymerase chain reactions. Statistics were performed using the SPSS for Windows (release 16.0). Results: Patients with normal peripheral nerve function OXLIPN were 14.3% homozygous for C, 28.6% heterozygous and 57.1% homozygous for T. The corresponding percentages for patients who developed OXLIPN did not differ significantly and were 5%, 25% and 70%, respectively. The majority of patients with mild OXLIPN were heterozygotes (50%, with 16.7% CC and 33.3% TT), whereas the majority of patients with moderate OXLIPN were homozygous for TT (85.7% with the remaining 14.3% being CT). Notably, the TT genotype was associated with increased OXLIPN compared to the genotypes containing the C allele (p= 0.046). Conclusions: The ITGB3 polymorphism at residue 33 appears to be unrelated to the development of OXLIPN but related to the grade of OXLIPN.Further study on this important clinical issue is warranted. No significant financial relationships to disclose.

Abstract
The objectives of this study were to evaluate a novel semiquantitative application of the bioluminescence test for screening newborns for Duchenne muscular dystrophy (DMD) and to use this technique in a pilot national program. The study was performed on the island of Cyprus, which provides ideal conditions for maximizing the prevention rate due to the small size of the country, the well-defined population, and the high degree of awareness of the public concerning genetic diseases. Guthrie spots were obtained through the national screening center for phenylketonuria and congenital hypothyroidism. The bioluminescence method for measuring creatine kinase (CK) in dried blood spots was adapted for use in a semiquantitative way. During the first 6 years of the program (1992-1997), we screened 30,014 samples and found 43 with initially high CK values. We were able to obtain repeat specimens in 35 cases. Of the repeat samples, 30 were found to have normal activity, giving a false-positive rate of 0.10%. Five boys had persistent CK elevations and were confirmed to be DMD or Becker (BMD) cases by DNA analysis and/or dystrophin analysis. The semiquantitative application of the bioluminescence assay of CK that we have introduced has proved to be a fast and reliable method for screening large numbers of samples for DMD. It has a low rate of false positives, which compares favorably with that of other DMD screening programs. Although it is early to evaluate its impact fully, the program seems to be bringing about the anticipated benefits to affected families.

Abstract
The olfactory social memory test, based on the recognition of a juvenile rat by a male adult rat, was used to investigate whether melatonin influences memory. Intracerebroventricular (i.c.v.) injection of 1.1 nmol melatonin shortened recognition time, while the melatonin ML1 receptor antagonist luzindole (1 nmol) exerted the opposite effect. The facilitating influence of melatonin was abolished in the presence of 0.5 nmol luzindole. The findings suggest that endogenous melatonin facilitates short-term memory.

Abstract
The social memory test was used so as to investigate whether brain histamine is involved in short-term memory. Histamine injected intracerebroventricularly (i.c.v.) decreased investigation time of a juvenile rat by an adult rat. A similar effect was elicited by i.c.v. administration of histidine. Compared with the control animals, rat pretreatment with alpha-fluoromethylhistidine (FMH), which inhibits neuronal synthesis of histamine, prolonged recognition time. The H3-receptor agonist immepip also prolonged investigation time, while the H3-antagonist thioperamide exerted the opposite effect. Treatment with histidine increased, while treatment with FMH decreased histamine levels in various brain regions. It is concluded that histamine released from histaminergic neurons facilitates short-term memory.

Abstract
In two different enriched populations of Leydig cells (called FI and FII) obtained from human testes (young patients: mean age 36 +/- 3 years, n = 6; aged men: mean age 73 +/- 2 years, n = 5), the dehydroepiandrosterone and testosterone in vitro outputs were increased in a dose- and time-related manners by hCG. Similar results were obtained when the Leydig cells were incubated in presence of either dbcAMP or 22R-hydroxycholesterol. In presence of either hCG or dbcAMP, the coefficient of stimulation (in terms of steroid outputs) was higher in FII when compared to FI. Conversely, the basal production of steroids was greater in FI than in FII, mainly for testosterone. The addition of increasing amounts of seminiferous tubule culture medium (STM) to the Leydig cell incubation medium led to a dose-related enhancement of the steroid production in both enriched-Leydig cell fractions under basal and hCG-stimulated conditions. Similar results were obtained in presence of increased seminiferous tubules length. Additional experiments realized with either concentrated STM or the coculture of seminiferous tubules with purified Leydig cells have confirmed the existence of a paracrine control of Leydig cell steroidogenesis by seminiferous secreted factor(s). A paracrine factor (or factors) from seminiferous tubular origin influences positively and with a high efficiency the Leydig cell function in humans, whatever the age.
